We all benefit from an open web that is secure, powerful, and fast. Over the past year, we’ve focused our efforts on strengthening the web in three areas:
- Rethinking how we can deliver a safe and secure web
- Adding the capabilities you need to build powerful, rich, and diverse applications
- Optimizing for performance, for users and developers alike
This post is a synopsis of the updates we shared during today’s keynote at Chrome Dev Summit.
Rethinking privacy from the ground up
We’ve continued work on the Privacy Sandbox and we are committed to developing an open set of standards that fundamentally enhance privacy on the web. Together with the web community, we’re building new privacy-preserving alternatives to third-party cookies or other cross-site tracking mechanisms. With the Client Hints API, we’re reducing the fingerprinting surface of Chrome, and we have two solutions for you to experiment with via our Chrome origin trials. The Click Conversion Measurement API measures ad conversions without using cross-site identifiers, and the Trust Token APIs help convey trust from one context to another without passive tracking.
Similarly, the security and privacy of extensions has become of utmost importance with hundreds of millions of people using over 250,000 items in the Chrome Web Store. We believe extensions must be trustworthy by default and it’s why we announced a draft proposal for a number of changes to our extension platform. After incorporating a number of different suggestions from extension developers, we’re ready to launch the stable release of Manifest V3 with the goal of increased security, more control and privacy for users, and improved performance.
With Manifest V3, remote hosted code is no longer permissible to prevent malicious extensions that abuse user privacy and security. Additionally, the new extensions model allows users to withhold sensitive permissions at install time. Lastly, a new approach to background logic with the introduction of service workers for background pages and a new declarative model for extension APIs provides users more consistent performance guarantees. Manifest V3 is now available to experiment with on Chrome 88 beta, with the Chrome Web Store accepting Manifest V3 extensions mid-January when Chrome 88 reaches stable.
Bringing powerful capabilities for advanced apps
Great examples are coming to life from developers who are building new experiences on the web. Gravit Designer makes it easy for users to read and write files with File System Access APIs and allows the use of specialized fonts installed locally with the new Local Font Access API. Adobe has made it easy for users to create stunning visual stories and beautifully designed content with their Spark web app.
Today, we are adding new capabilities for Progress Web Apps (PWAs) to increase their discoverability by being listed in the Google Play Store. In Chrome 86 we gave you the ability to list your PWA in the Play Store using a Trusted Web Activity. We’ve now made it possible for you to start accepting payments using the new Digital Goods API in Chrome 88.
Optimizing for performance
Chrome’s performance—speed and usage of resources like power, memory, or CPU—has always been top of mind so you can deliver the best experience for all our users.
Since we announced our Web Vitals initiative, they are being increasingly used to measure web page performance. Google Search announced new signals to search ranking will include Core Web Vitals starting in May 2021. In addition to the Chrome User Experience Report, Search Console’s Core Web Vitals report, and many other Google tools, other providers like Cloudflare are surfacing Core Web Vitals as web page performance metrics.
